Title: Process for producing cmos having doped polysilicon gate by outdiffusion of boron from implanted silicide gate
Inventor: GIERISCH HEIKE D
IPC: H01L21/82
Filed: 1986-11-25
Granted: 1995-03-15
Abstract: A process for the production of highly integrated circuits contaiining p- and n-channel MOS transistors including gate electrodes which consist of a doped double layer of polysilicon and metal silicide. The gates are doped with boron and are produced by diffusion from the metal silicide layer which has previously been doped with boron by ion implantation into the undoped polysilicon layer. The metal silicide layer preferably consisting of tantalum silicide is provided with a masking layer consisting of SiO2, and the structuring of the boron-doped silicide gate and the masking layer is carried out after the boron atoms have been diffused in. The process serves to safely avoid undesired boron penetration effects which considerably influence the short channel properties of the transistors. The process is used for the production of CMOS-circuits having a high packing density.

Abstract: The break-in method is such that, when an attendant perceives a telephone  subsciber  on  the  line,  the  attendant  breaks  in forcefully upon  the  subsciber's  call  currently  on  the  line, changing the  present  call  to  a  conference-call  and,  if  the attendant hangs  on  the  phone,  the  subscriber  waiting  to  be switched breaks into the conference call replacing the  attendant. The method comprises the steps of checking a  simple  call  state; allocating  the  conference-call  circuti;  intervening   in   the attendant break-in  state;  and  checking  the  attendant  hang-on state. The method allows the waiting  or  reserved  subscriber  to break in a conference-call state by  use  of  the  conference-call circuit while continuously holding subscibers present line.

Title: Complex coding method of voice synthesizer
Inventor: LEE YUN-KEUN
IPC: G10L19/04
Filed: 1989-10-31
Granted: 1992-05-18
Abstract: The apparatus on which the method is applied includes: a  key board (1), a personal computer (2), an interfacing section (3),  a voice data ROM (9), a program ROM  (8)  and  a  D/A  converter.  A voiceless sound is subjected to an ADPCM  coding,  while  a  vocal sound is subjected to an  LPC  coding.  A  DSP  (5)  converts  the inputted data to a form corresponding to  the  pronunciation,  and divides each sound into  initial  sound,  middle  sound  and  last sound. Then the program ROM (8) reads the data from the voice data ROM (9) to carry out an ADPCM coding in the case  of  a  voiceless sound, and to carry out a voice  synthesis  by  means  of  an  LPC filter in the case of a vocal sound. Thus the voice quality can be improved, and the data can be sufficiently compressed.

Abstract: In a communications system having transmissions containing certain information-of-interest (147, 149) at predetermined intervals in the transmission, there is provided a method for isolating and processing that information-of-interest. The method is characterized by sensing the start of a transmission (141) and isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time (145) from the sensed start of transmission (141). Thus, the information-of-interest is isolated principally on the basis of elapsed time. The method for isolating and processing that information-of-interest is further characterized by sensing (249) the start of a transmission from the received signal power of the transmission exceeding a predetermined threshold (259); AGCing the transmission (233) and attenuating the AGC'd transmission from a maximum level to a desired level before the information-of-interest is expected to arrive; isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time from the sensed start of transmission, by timing (263) the expected interval between the instant that the start of the transmission is sensed and the predetermined instant that the information-in-interest should arrive (whereby the information-of-interest is isolated principally on the basis of elapsed time); tagging the information (247) isolated about that instant for processing; and beginning processing (275) with information just preceeding the isolated information (whereby the reliability of the information detection is enhanced by one-to-several bits). <IMAGE>
